Vibrator

Abstract

A vibrator B includes a substrate 31, a coil 33 supported to the substrate 31 and a vibrator member 40 disposed in opposition to the coil 33 and capable of vibrating along the axial direction of the coil 33. The vibrator member 40 includes a weight 43, a magnet 42 polarized along the axial direction of the coil 33, and a supporting member 41 for supporting the magnet 42 with allowing displacement thereof along the axial direction of the coil 33.

Description

technical field [0001] This invention relates to vibrators that convert electrical signals into vibrations. Background technique [0002] In recent years, vibrators that convert electrical signals into vibrations have been used in various devices. For example, a mobile phone or the like has a function of notifying the user of an incoming call by vibrating instead of ringing. Portable game machines and game machine controllers have a function of providing vibration according to the game situation in order to enhance the sense of reality. In addition, it is also applied to a purpose of providing a tactile sensation when a user touches the panel by being incorporated into a touch panel. [0003] This type of vibrator is, for example, fixing the coil to the frame, and elastically supporting the frame by the magnetic circuit part through the suspension, and disposing the coil in the magnetic gap constituting a part of the magnetic circuit. There is a heavy object in the magneti...

Problems solved by technology

[0006] The vibrator of Japanese Patent Application Laid-Open No. 2003-033724 has difficulty in improving the positioning accuracy of the above-mentioned coils

On the other hand, although the vibrator of Japanese Patent Laid-Open No. 2007-184812 can improve the positioning accuracy of the coil, holes for positioning are provided on each component, which increases the manufacturing cost of each component.
